RF Signal Recorder - Spectra Lab

Duplicate real-world RF environments in the lab

Spectrum Defender is a RF Record and Playback instrument that allows you to capture and reproduce any signal in the electromagnetic spectrum. Whether you’re recording one channel or many, Spectrum Defender captures every pulse and transient signal with high fidelity.

Multiple channels allow you to stimulate on one band and record on another. Unlike traditional RF Recorders, Spectrum Defender allows you to do quality control in the field including immediate signal playback. Sharing recordings with colleagues is quick and painless with multiple options for high-speed data offload.

Find Your Exact-Fit RF Recorder

Choosing an RF recorder can be complicated, but it doesn't have to be. We offer many configurations and customizations. We're happy to advise you on which is best for your needs.

Model 3863

Record and play two synchronized RF channels

Model 3863 allows you to capture and reproduce two RF channels anywhere in the spectrum between 30MHz and 26.5GHz. You can configure the two channels to be time aligned, phase coherent, or fully phase aligned. This instrument is perfect for analyzing interactions between signals in different parts of the spectrum or stimulus-response applications.

Model 3823

Record one wideband RF channel in a congested spectral environment

Model 3823 allows you to record a wide block of RF spectrum using a single RF channel. The super-het RF downconverter architecture and built-in LNA is optimized to retain signal quality in the most difficult and congested spectral environments. Additional RF pre-selector options allow you to knock down large out-of-band interferers and really dial in your recordings for maximal fidelity.

Model 3865

Generate eight phase-coherent arbitrary waveforms at RF frequencies

Model 3865 is unlike any other RF signal generator you’ve ever used. This instrument can simultaneously stream eight different arbitrary waveforms to eight independent RF output channels. Each arbitrary waveform can be minutes or hours in duration. Choose the phase-aligned option to create tightly aligned beams across wide bandwidths.
